Accountants don't have to do that anymore. Since 2011 where they changed the cost basis law (brokers have to report all cost basis from that date on) brokers have to give you wash sale info. It should be on your 1099 - there is a column there for them to report it. Very easy now. And they do all the work since wash sales are just a basically a delay - they take those disallowed losses and add them to your new cost basis so you basically do get them. It is all done for you by your broker now.
